My site is reincarnated as http://sofajpl.com .
There you will find the SofaJpl astronomy DLL, the production release of
the Lunar program, and the beta release of the next Lunar version,
version 4.4.
New in Lunar 4.4:
• it remembers the JPL ephemeris and leap second files from the last
run, as well as the user latitude, longitude, and height
• a "center of light" option for planets (thank you Antoine Couëtte)
• "Horizons compatibility" option to generate coordinates compatible
with the JPL Horizons online calculator
• "solar eclipse" mode to apply the standard semidiameter and
corrections for center of figure in the Astronomical Almanac predictions
• If a lunar distance solution fails to converge in a reasonable number
of iterations, the program warns of possible degraded accuracy but does
not throw an exception.
• quite a few improvements in the output data
The program itself has given complete satisfaction in my tests, but the
documentation in this beta release is not yet adequate.
